I test started the engine yesterday, after having built in a new counter balancer. The difference was huge! Vibrations were down to a minimum! On Tuesday its off to a local track, for further testing. Skickat från min SM-A310F via Tapatalk

Changing the length is not an option. [emoji6] I fitted both tubes yesterday, and tack welded them. The step from d35 to d38 had to be 80mm further down stream to get past the cb housing. Thats the only sacrifice. Skickat från min SM-A310F via Tapatalk

It is a bakelit (?) reinforced with a fabric weave. It's a common mtrl for toothed gears. The combination with a steel gear can be run dry, without having to soak the new gear compartment in oil. Skickat från min SM-A310F via Tapatalk

It is necessary to mount 90WCu10 inserts to obtain the calculated imbalance. I do not know the weight after this latest upgrade. I'll have to get back to you on that matter. According to the simulations, the amplitude will be reduced by appr. a factor of 6. Skickat från min SM-A310F via Tapatalk
